what about
connect(play, SIGNAL(clicked()), mLocalPlayerIO, SLOT(slotPlay()));
assuming mLocalPlayerIO is your KGameIO derived class that has a slot called 
"slotPlay()".

Another solution (I usually prefer that one):
connect(play, SIGNAL(clicked()), this, SLOT(slotPlay()));
and
MyWidget::slotPlay()
{
 mLocalPlayerIO->doSomthing();
}

What about KPlayer::findRttiIO(rttiOfYourKGameIO) ?
(don't forget to check for NULL in case of errors)

The mLocalPlayerIO above can be replaced by a call to findRttiIO() of course 
(and maybe a cast to the derived class)
